close by behind the inside of the flange Hi. In the mounting of the water closet l8 on the subbase l suitable sealing material of plastic nature is provided between the rib 20 and the water closet to effect a good fluid-tight connection between these parts. Note that the rib 20 along its laterally outside face is preferably formed with a re-entrant groove in which the sealing material lodges in locked position.

An important feature of my invention is that formed integrally with the endless upstanding flange I2 of the sub-base I0 is a relatively flat basin 24 which slopes downwardly and inwardly towards an integral connector collar 26 positioned in the basin 24 at a point opposite the discharge outlet 28 of the water closet H3.

The connector collar 25 is received down in an opening 30 in the floor l4, and is adapted to receive and surround the soil or I. P. S. pipe 32. The connector collar 26 is provided with a flange or shoulder 34 at its lower end which substantially touches the pipe 32., and suitable sealing such as oakum 3B and solidified molten lead 38 seals between the connector collar 25 and the pipe 32.

The outlet or discharge opening 28 of the water closet is is usually provided with a flat circular flange it which is preferably adapted to be en gaged in sealing relation with the top of the connector collar 25, and this is achieved by the provision of a rubber or putty washer 42. However, it is within the concepts of my invention that no sealing washer 42 be employed as described, in which case the basin 24 and the sealing flange 2B are solely relied on for sealing, and I have found that with the installation illustrated and described the basin and flange alone do an excellent job. It maybe within the discretion of the plumber installing the equipment whether the single or double seal is employed, but as noted, I usually prefer the double seal.

Formed integrally with the sub-base II] are bosses 4B which receive wood screws 48 for securing the sub-base it to the floor l4. Likewise, the bosses '45 receive threaded studs which extend up throug horizontal flange portions of the water closet l8 as best seen in Fig. 3, the studs being capped by cap nuts 52 for securing the water closet it to the sub-base ii). If desired, in order to look the stud washer 55 may be positioned over each stud above the boss 58 and a half nut 56 can be used to clamp the washer and the stud tightly in p0- sition. In the drawings, linoleum or other floor covering Bil is shown completing the installation.

From the foregoing, it will be recognized that the various objects of my invention have been achieved by the provision of a relatively simple, and inexpensive sub-base which greatly speeds up and facilitates the mounting of a water closet upon a bathroom floor and in sealed relation with a soil pipe. The sub-base is generally made of a high-grade cast iron, and may be appropriately enameled or porcelainized on the outer surface of the upstanding flange l2. The securing of the sub-base to the floor, in the manner described, followed by the attachment of the water closet to the sub-base makes for a considerably improved and rigid installation which will function in leak-proof manner substantially for the life of the Water closet, and often regardless of sagging floors. Should any leak develop at the seal 43 and water escape out to the basin 24 the seal provided between the flanges 12 of the sub-base and It or the water closet prevents any leakage Ell in position a lead I.

the bottom of of the connection. Also, the normal drainage from the flat sloping basin 24 is such that water will flow back to the connector collar 26 and out the soil pipe 32 once the pressure or the water flushing operation is removed.

While in accord with the patent statutes, I have specifically illustrated and described one best known embodiment of my invention, it is to be particularly understood that I am not to be limited thereto or thereby, but that the scope of my invention is defined in the appended claims.

4. In combination, a Water closet, an endless bottom edge flange on the water closet, a sub-- base, an endless flange on the sub -base fitting under the bottom edge flange of the water closet, means on the sub-base for preventing the lateral displacement of the flanges on the water closet and sub-base, means sealing between the flanges, a relatively flat shallow basin in the sub-base exconnector collar, and a soil pipe received in and sealed to the connector collar.

5. In combination, a water closet having a discharge opening, an endless bottom edge flange on the water closet, a sub-base, an endless flange on the sub-base fitting under and supporting the lateral displacement of the water closet on the sub-base, an integral relatively fiat shallow basin in the sub-base extending from the endless flange inwardly and slightly downwardly,

water closet to the sub-base.

6. A combination as in claim 3 wherein the laterally outer surface of the sub-base endless flange is exposed, and means seal the discharge openfrom the water base to the floor engaging surface thereof, and wherein both means securing the sub-base to for engaging screw means to secure a water closet to the sub-base.

9.
